This invention relates to improvements in portlights andinore particularly to the construction of port hole covers andthe means of fastening these shut. Among the objects 5 of the invention is to providel a cover having yieldable packing adapted toV vbe pressed against some suitable portion of the traine work and a locking device carrying means for applying pressure to the cover at widely lc separated points for holding the cover securely closed and compressing the packing. The packing serves the twofold purpose oi cushioning the glass carrying 'frame and ot sealing the port hole. Another object is to `il provide means for quickly engaging the locking device which is securely fastened at the leisure of the operator by the actuation of the pressure applying means. Y

In the accompanying drawings one praey 20 ticable embodiment of my invention is illustrated, in which drawings Figure 1 shows in perspective the port light detached and in closed position. Fig. 2 is a cross sectional representation of the device represented in 95 Fig. 1, but mounted on the frame work ot the ship and in a larger scale, and Fig. 3 is a face view of a port light of a shape differing from that shown in Fig. 1.

The cover for the port hole is shown in the illustration in the form oil a. door having a metal frame 5, furnished with a light of glass 6, this being held in position by removable stops 7, and cushioned at all its points of contact with the frame by a bent over strip 8.

The door or cover is hinged to a metal frame 9 which has a flange portion 10 `igor passing through the opening in the side of the ship, illustrated in the drawing by a pair of wooden timbers 11. The frame 9 also has a flat portion 12 adapted to rest against 'the flat outer side of the ship body. In the illustration this fiat portion 12is shown let into a recess andheld in position by screws 18.

The frame 11 is shown carrying at one side f5" two sets of hinge members 111-14, each pair of which carries a pivot boit 15 upon which bolts the hinge members 16 fast with the cover or door trame 5 are'mounted. lt will be noted, especially in Fig. 2, that the pivot receiving opening 17 ot hinge member 16 ing is also afforded this means of comis" elongated so as to not interfere with .the movement of the cover whensubjected to the pressure applying means presently to be de"-v scribed.I j y t the side of the frame 9, opposite each of the hinges, there isrformed an extension 18 to which is pivoted a clevis 19 which constitutes part or' the locking device.

4The outer side ofthe cover frame 5, i. e. the lower side in the Fig. 2"illustration,` is provided with afgroove adaptedto register withthe upstanding edge of the flange 10 where `this protrudes inwardly beyond the inner'face oi' the framing members 11. This groove is preferably wider by considerable extent than the thickness loi-'"widthfor the Y iiange 10. In this groove there', is inserted someA suitable packing or cushioning material 2O for engaging the extension of the flange 10.

The locking means is shown in the tornil of a bar 21. One `bar 21 only is illustrated in Fig. 3y which the cover 51* is shown as cir cular. And the frame work upon which i't ismounted, as represented by the fiat portion "5 12 is also round. In the Figure 1 construction in which the parts are rectangular two bars 21 are employed. It Vwill be seen that each bar 21 has a pair of hinge members 22 which engages one ot the pivot bolts Preferably these hinge members 22 lie inside of the hinge members 14 and lieV on the opposite'sides of' the hinge member 116. This makes avery strong and rigid construction, V as will be obvious. v E 8"' The :tree endlof the bar 21 has4 ahook 23 which is in position to engage theshackle 19 when thev door is shut, and the locking bar 21 isbrought into its initial locking position.

i The bar 21 carries adjacent its respective 90' ends or ina position to overlie the packing materialy 20, pressure applying' devices illus tra-ted inthe form of thumb screws 24.. By vineans ot these thumb screws,I after `the shackle 19 is engaged withthe hook 23, theV cover may he securely pressed against the trame 9 to such aneXt'ent that water and wind cannot pass'. "A certain amount of cushionpression.

During the compression of the packing by the pressure applying means the cover is permitted to freely move relatively tothe hinge pivot, this being permitted by the extension 17 in its hinge. A l

Not only do the packing 20 and the pressure applying devices 24; hold the cover securely in position, but the pressure also' has the effect of securing the locking device.v

With the parts in the positions illustrated in the drawing, when it is desired'to unfasten the port light or cover, the operator releases the screws 24 which then make it possible to remove the clevis 19 from the hook 23,-Whereupon. the operator may swing the bars 21 on theirhinges which will then leave the cover, which is a form of the door, free to be opened as maybe desired. e

Tith this cover door open, when vit is desired to secure it in position the operator closes the door into the position illustrated, swings the bar, or the pair of bars 21, across the cover and engages the clevis 19 with the hook Qivhich will preliminarily holdv the door closed, after which,r at hisfleisure, the operator will apply pressure by turning in the screws 24 until the packing material 20 is sut'ticiently compressed to hold the door rigidly in position and prevent the entrance of wind and water.

Although the details of but oneform of the invention have been illustrated and described, yet it will befobvious'that various changes may be made Within kthe scope of 'the claims without departing from the spirit of the invention.

I claim:

1. In a port light, the combination with a Y frame adapted for application to the Iport hole of a vessel, the frame having at one side a hinge comprising a pair of hinge members supporting a pivot pin and at the opposite side an extension, and a clevis pivoted to such extension, ot a cover having a hinge member provided with an elongated opening and mounted on the pivot pin, a locking bar having a pair of hinge members located inwardly of the hinge members of lthe frame and interposed between sueh members and the hinge member of the cover, the locking bar being provided at its free endwith a hook for engaging the clevis, and a pressure applyingl screw carried by each end of the bar located in position for pressing the cover against the frame. and the bar against the pivot pin and the clevis.

2. In a port light, the combination With a 'trame adapted for application to the port hole of a vessel, the frame having at one side a hinge member supporting a pivot pin and at the opposite side an extension, a clevis carried by such extension, a cover having a hinge member mounted on the pivot pin a locking bar hinged to the frame, suoli bar eing provided at its free end with a hook for engaging the clevis, and pressure applying screw means carried by each end of the bar for Dressing the cover against the frame and the bar against the clevis.

3. In a port light, the combination with a frame adapted for application to the port i hole of a vessel, the frame having at one side ly of the hinge members of the frame and interposed between such members and the-hinge member of the cover, the locking bar being ,provided at its free end with a hook for engaging the clevis, and pressurey applying means carried by the. bar for pressing the cover against the frame and the bar against the clevis.

In Witness whereof, I hereby ailix my signature this 11th day of February, 1929.
